In this example, I am going to show you how to passthrough the Samsung EVO 840 SSD driver to ESXi 7.0 Update 2 via RDM(raw disk mapping ).

I have 3 SSD in the setup, Crucial MX500 1TB, Samsung 830 EVO 256GB and Samsung 840 EVO 250GB. The 1TB SSD is the main storage and hold the VPS for FreeNas 11.2 (Yes, I know the newer FreeNas 11.3 and TrueNas 12 are arleady available). Some of the photo are from EVO 830 and some of the screenshots are from EVO 840.


If you already read documents from other sources, here is the key notes to make it success.

• Make sure the target disk is not shown in storage, otherwise the mapping will failed.
  

• You need another disk place to store the RDM mapping link (will explain it later)
  

I designed this part and printed in 3D printer just to protect the battery connector for Trex electric bike (Bion-X system)

这个帐篷是六人帐篷,但是实际上只有二个人睡.帐篷的内部空间足够大，所以我们把二个卧室打通,一个卧室放气垫床，另一个卧室放投影机。
投影机放在一个笔记本电脑桌上,一来比较平整稳定,而且万一帐篷底部进水也不致于损坏投影机
屏幕是一个展示板的背面,大小正合适,也算是费物利用.
屏幕架是音乐的乐谱架,也是因为手头刚好有.
投影机是ViewSonic M1, 自从买了4K的 ViewSonic X10-4K后，这台投影机也基本闲置不用了，用在camping刚好。而且内置电池，即使没有市电也可以使用。

缺点：白天亮度不够，分辨率较低
优点：给野营增加了额外乐趣

Please note, some camping sites have restrictions for playing music on site, so you might want to use headset with the projector.

I received the second HP OMEN 15-en1507na gaming laptop from Currys since 24/Aug (the first laptop is having the screen flicker issue, please see my other thread). I am very happy with this laptop, especially the excellent screen and performance. The only issue I am having is it is making non-wind whirring fan noise which is annoy on a quiet room.

The CPU utilisation is about 3% and both CPU and GPU temperature is about 44 degree Celsius.

My another laptop Lenovo only makes pure wind noise on both low and high fan speed. 

I am wondering should I return this laptop.
Update 1: I plan to keep this laptop and will try below solution:
    1, keep the laptop running on battery on productive work
    2, Add external laptop cooler
